Save

The inverse of Pule repetition time gives

Detailed Solution: Question 10

The inverse of Pule repetition time gives PRF (Power Repetition Frequency), other abbreviation denotes PRT (Power Repetition Time), PSR (Power Supply Rejection), MSR (Mark-to-Space ratio).

Test: Classification of Oscillator - Question 11
Save

Which of the following is not an example for non-sinusoidal oscillator

Detailed Solution: Question 11

Since crystal oscillator produce a sine wave output it is not a non-sinusoidal oscillator.

Test: Classification of Oscillator - Question 12
Save

Which of the following is not an LC oscillator

Detailed Solution: Question 12

Crystal oscillator is not an LC oscillator because it does not contain any L or C.
